The proof is the fact there are junk yard parts installed in the car and the knuckle and rotor are the wrong size for the car, and as I said, if you take a magnet to that section of the car its the only place on the car that the magnet won't stick to it, like the section has been replaced.
I guess the best I could do is get the numbers off the parts and attempt to call around and find out which junkyard they came from, and get dates to prove I didn't do it, if I did that would I have a case, or am I still out of luck cause its a used car?
